Zach Bryan played a surprise 40-minute acoustic set Tuesday night at the Sagebrush in Austin, Texas.  The first 100 fans to show up got in, and they also received FREE beer courtesy of Zach.

If you’ve been following Zach, you probably noticed he’s participating in Dry January.  Well, he seemed to cave Tuesday night by toasting with the crowd then later tweeting quote, “I am a weak man” and “Back to bidness tomorrow”.  (Whiskey Riff)
